摘要： A fuel pressure regulator (20) which stores a fuel pressure detecting part (21) formed by a diaphragm part (21a) for detecting the pressure of fuel delivered from a fuel pump (4) and a current control part (22) for analogically controlling a current flowing to the fuel pump (4) by a signal from the fuel pressure detecting part (21) and which is provided on the upper surface of a cover part (3) of a fuel feed device (10) to be load in an opening (2a) of a fuel tank (2), wherein the fuel pump (4) is operated so that it delivers fuel according to a flow rate requirement of an injector installed on an engine, and thus the operating current of the fuel pump (4) is reduced and also the operating noise is reduced.
